Bench And Long-Hole Drilling T51 (2″)


Bench and long-hole drilling using T51 drill rods with a diameter of 2″ (50.8 mm) are common practices in mining, quarrying, and similar industries. Here are some key points about T51 drill rods and their use in these applications:

  1. Diameter: The 2″ (50.8 mm) diameter is a standard size for drill rods in many rock drilling applications. This diameter provides good strength and durability while allowing for efficient penetration into the rock.
  2. Material: T51 drill rods are typically made from high-strength steel alloys that are specifically designed for rock drilling. These materials are chosen for their ability to withstand the forces and vibrations encountered during drilling operations.
  3. Bench Drilling: Bench drilling involves drilling shorter holes from a raised or “bench” position, such as along the edge of a pit or quarry. T51 drill rods are suitable for this type of drilling, especially when the rock is harder or more abrasive.
  4. Long-Hole Drilling: Long-hole drilling refers to drilling deeper holes, often exceeding the height of the bench. T51 drill rods are also suitable for long-hole drilling applications, providing the necessary strength and durability to reach the desired depths.
  5. Features: T51 drill rods often have threaded ends that allow them to be connected to other rods or to the drill bit. This allows for longer drill strings to be assembled for deeper drilling. The rods may also have other features, such as coatings or special designs, to improve their performance and durability.
  6. Applications: T51 drill rods are commonly used in mining, quarrying, and other industries where rock excavation is necessary. They are suitable for a wide range of rock types and drilling conditions.
  7. Safety Considerations: When using T51 drill rods for bench and long-hole drilling, it is important to follow safety protocols and procedures. This includes wearing appropriate protective equipment, ensuring the drilling equipment is properly maintained, and adhering to industry standards and regulations.

Remember, the specific requirements and recommendations for drill rods may vary depending on the manufacturer, the type of rock being drilled, and the specific needs of the drilling operation. Always consult with the manufacturer or a qualified drilling expert for more information.
